“…Because wind energy and solar energy are greatly affected by the natural environment, it is difficult to widely replace petrochemical fuels in a short time [8]. However, the biodiesel produced by animal and vegetable oil in ester exchange reactions, not only has the equivalent petroleum diesel combustion, but also has environmentally-friendly, renewable [9], and other positive features, making it one of the ideal diesel fuels to substitute petroleum [10]. Biodiesel is a clean energy source and is considered as the most viable replacement of fossil fuels due to its biodegradable nature [11], low emissions, carbon neutrality, and nontoxicity [12].…”

In this paper, biodiesel was used as an alternative fuel to investigate the combustion and emission characteristics of a four-stroke diesel engine, in terms of cylinder pressure, heat release rate, cylinder temperature, brake thermal efficiency, brake specific fuel consumption, nitrogen oxide, soot, carbon monoxide, and hydrocarbon. Firstly, a diesel engine cylinder model was developed by AVL-Fire software coupled with CHEMKIN code to simulate the injection and combustion of biodiesel with a kinetic mechanism with 106 species and 263 reactions. Then, the simulation model was validated by experimental results under 100% and 50% load conditions and used to simulate the combustion process of a diesel engine fueled with pure diesel, biodiesel, and biodiesel–diesel blends with 10%, 20%, 30% biodiesel by volume, respectively. The results showed that the brake specific fuel consumption increased with the increase of mixed biodiesel ratio. The brake specific fuel consumptions of B10, B20 and B30 increased by 1.1%, 2.3% and 3.3%, respectively, compared with that of D100. The combustion and emission characteristics of the diesel engine are improved. Therefore, biodiesel can be used as an alternative fuel for the diesel engine. The diesel–biodiesel fuel can improve the combustion and emission characteristics of the diesel engine.

“…From the FT-IR and GC-MS tests, it can be seen that the compound that affects fuel quality is Hexadecane (C16H34) which is closely related to determining the quality of diesel fuel [29]. The Hexadecane compound has a higher percentage of fuel mixed with nanoparticles, up to 5.48%, compared to B30, which is around 3.83%.…”

Biodiesel is used as an alternative fuel that is renewable and environmentally friendly. Biodiesel has several disadvantages compared to diesel: energy with lower heating value, volatility, and viscosity. One of the efforts to reduce the weaknesses of biodiesel is using additives. This study aims to determine the performance of diesel engines from the addition of nanoparticles to biodiesel. This study uses several test samples, including B30, B30+Al2O3 30ppm, B30+Al2O3 50ppm, B30+Al2O3 70ppm, and B30+Al2O3 90ppm. Each sample was tested on a diesel engine. The results showed that the fuel mixture with Al2O3 nanoparticles increased Cylinder Pressure by 13%, Net Heat Release by 41%, and Brake Thermal Efficiency by 76% at a 3kg load. The Smoke Opacity and Specific Fuel Consumption obtained are better than B30.

“…Low-and hightemperature chemistry are implemented in that scheme which involves 1188 species for 4959 reactions in total. The simulations showed that in the low-temperature oxidation region, n-hexane mainly reacts via H-atom abstraction by hydroxyl radicals coming from the decomposition of the KHP 2,4 and KHP 3,5 (Table 4). A shift in temperature was observed of all concentration profiles between the modeling and the experiments.…”

“…Normal and branched alkanes are major constituents of commercial liquid fuels [1][2][3]. Recently, n-alkanes such as n-hexane have been used as additives to conventional fuels for improving the combustion properties and efficiency of diesel engines [4][5][6]. The ignition, combustion, and oxidation of primary reference fuels has already been the topic of many studies conducted over a wide range of conditions.…”
